For the love of honey.........It's just the tactile and olfactory delight of it all....the hair, or lack therof....the smoothness, the roughness, the scent.........not funky, but musky...the veins (omg, I love them so)....pheromones emitted.......tongues flicking and the wetness...(me getting wet and the ever popular precum).....it's extremely deliberate, yet there are aspects that the body controls.......no brain needed!! Is that a good explanation? I give as good as I get!!!
